Abstract
PURPOSE:To obtain the titled fiber of both high strength and high modulus improved in drawbacks such as easy fibrillation, by kneading a polymer constituted of specific unit and a molten polymer of liquid crystal nature differing in the structural units followed by spinning, drawing and heat treatment. CONSTITUTION:First, (A) a polymer having >=90wt.% of the domain constituted of recurring units of respective formulas I and II is kneaded with (B) a molten polymer of liquid crystal nature different from the polymer A in the recurring units so as to contain 0.3-40wt.% of the polymer B. Thence, the resulting product is spun followed by drawing and then heat treatment, thus obtaining the objective fiber. Preferably, the polymer B is constituted of recurring units of respective formulas I and III.
